Abstract of Invention Title of the Invention; BICYCLE PEDAL STRUCTURE CAPABLE OF TRIGGERING AUXILIARY POWER A bicycle pedal structure capable of triggering auxiliary power is provided and includes a base, sleeve unit, crankshaft, two pedal cranks and treading force sensing unit. The sleeve unit includes a first sleeve and second sleeve disposed in two opposing openings of the base, respectively, The first and second sleeves are fitted around the crankshaft so that the crankshaft is rotatably disposed in the base. The pedal cranks are respectively coupled to two ends of the crankshaft and extended therefrom in two directions which are opposite and substantially perpendicular to the crankshaft, The pedal cranks each have .a pedal subjected to a treading force, thereby rotating the crankshaft The treading force sensi ng unit has piezoelectric disks at least disposed on the first and second sleeves and above the crankshaft The bicycle pedal structure adapts to mount on a bicycle frame and connects with a drive control systern to receive therefrom digital modularized auxiary power. 14 fr ~ -'-j |
